EtienneT on SubSonic magic

Oh yeah, those are the properties you should set in your object data source for better results:

SelectMethod="FetchAll"
SelectCountMethod="GetCount"
SortParameterName="sort"
EnablePaging="true"

So with this, you use the default FetchAll method, you'll have paging and sorting by default. Don't forget to enable paging on your GridView too.
